Sexual reproduction remains an evolutionary puzzle because it is costly compared with asexual reproduction, yet it is widespread across life. The piece surveys leading explanations for why sex persists and why its forms vary so dramatically.

Retraction Note: Sub-second periodicity in a fast radio burst
Summary
A paper reporting sub-second periodicity in a fast radio burst has been formally retracted. The retraction withdraws the claim from the peer-reviewed record.
Why it matters
FRB interpretations are highly sensitive to timing structure, so removing a marquee periodicity result resets theory priors and observational priorities.

What’s the Point of Sex, Anyway?
Summary
Sexual reproduction remains an evolutionary puzzle because it is costly compared with asexual reproduction, yet it is widespread across life. The piece surveys leading explanations for why sex persists and why its forms vary so dramatically.
Why it matters
Understanding why sex exists determines how scientists model evolution, predict adaptation, and interpret genetic variation in nature and health.

T. rex took 40 years to reach full size, scientists find
Summary
A study of 17 tyrannosaur fossils estimates that Tyrannosaurus rex took about 40 years to reach an adult mass of roughly eight tons. That timeline is about 15 years longer than common prior growth estimates.
Why it matters
A longer ramp to adulthood reshapes estimates of T. rex ecology, including how many apex predators existed, how they competed for prey, and how quickly populations could recover from losses.
